Odesa in context: Street-network sprawl trends

The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Odesa plotted against Odessa and Ukraine. The SNDi of new construction in Odesa was at its lowest in 1976-1990, compared to Odessa which rose steadily and Ukraine which rose steadily. Most recently, Odesa's incremental SNDi rose from 2.77 to 3.3 between 1991-2005 and 2006-2020. In terms of the aggregate network, Odesa ranked 1st out of 2 cities in Odessa and 28th out of 75 in Ukraine as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

In new street additions, Odesa built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Baltimore built increasingly disconnected streets from 1975 through 1976-1990, then improved and Kazan built increasingly disconnected streets over time. Looking at the full network, Baltimore and Kazan both became progressively more disconnected, while Odesa became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Odesa and Baltimore have been growing further apart in their street-network character since 1975.
